Not just your ordinary light bulb

Replacing the bulb in your garage door opener.....

Regular everyday light bulbs will often burn out quickly in automatic garage door openers .
Garage door openers produce a lot of vibration, which can kill incandescent bulbs prematurely. To fix the problem, tighten all the bolts on your unit and make sure it’s solidly mounted to the ceiling. Then, install a “rough service” bulb (available at hardware stores and home centers). These bulbs have heavy-duty filaments with extra support wires to keep them from breaking. The average opener light is on only about four minutes on average a day, so energy efficiency does not really come into play.
